Searching for the Proton's Missing Spin: Small- Helicity Evolution Equations and Their Analytic Solutions
Jeremy Borden
The proton spin puzzle denotes the challenge of describing the proton's spin in terms of the angular momenta of the quarks and gluons which comprise it. These quarks and gluons car…

Analytic Solution for the Helicity Evolution Equations at Small and Large
Jeremy Borden, Yuri V. Kovchegov
We construct an exact analytic solution of the revised small- helicity evolution equations, where the contributions of the quark-to-gluon and gluon-to-quark transition operators…
